Game Engine License & Portability Navigator
Create a web app that helps modders, preservationists, and indie developers determine which legacy engine codebases are official, unofficial, SDK-only, legally usable, and portable to target platforms. The discussion shows repeated confusion around repositories, licensing, and what code actually contains the engine versus game logic.
これが重要な理由
You want to port, study, or build on a classic game engine, but the first challenge is figuring out what code is actually usable. Some repositories look official yet only expose mod hooks or game-specific layers. Other projects reimplement the engine, but their legal status and completeness are unclear. You can lose a weekend reading forum threads and repository trees before discovering that your target path is blocked by middleware, missing engine layers, or license restrictions. What you need is a fast way to understand provenance, legal boundaries, and technical viability before investing engineering time.

- Launch a searchable directory with filters for commercial use, modding, and target OS
- Add portability scorecards for Linux, Windows, ARM, and niche operating systems
- Implement an engine decision wizard based on user goal and legal tolerance
- Add watchlists for repository updates and licensing changes
- Publish 10 long-tail comparison pages targeting search demand
- Enable paid features for saved collections, exportable reports, and team notes

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Most users may only need one-time research, making subscriptions harder to retain.
- 2The safest stance on licensing may feel too cautious to users seeking definitive commercial answers.
- 3Search traffic might be decent but fragmented across many small engine communities, slowing growth.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
Roughly eight comments revolved around confusion between SDKs, full engines, unofficial reimplementations, and licensing limitations. Multiple participants corrected each other on what specific repositories actually contain, which indicates a clear information-architecture problem rather than a lack of raw technical interest. That confusion creates wasted time and raises the value of a structured navigator that clarifies what is usable and portable.
